Western Blotting (WB), Immunohistochemistry (IHC), ELISA
Purpose
Rabbit polyclonal antibody raised against synthetic phosphopeptide of IRS1.
Specificity
Reactivity occurs against human IRS1 pS307 protein and This antibody is specific to the phosphorylated form of the protein. Reactivity with non-phosphorylated human IRS1 is minimal by ELISA.
Cross-Reactivity
Chicken, Cow, Dog, Human, Monkey, Mouse, Pig, Rat
Characteristics
Antibody Reactive Against Synthetic Peptide.
Immunogen
Synthetic phosphopeptide corresponding to residues surrounding S307 of human IRS1.
